Console Error

There are no errors in the console.
For more information about the error, I connected the test build to bungeecord
All I saw in the bungeecord console after setting the prefix: [Stive] disconnected with: SocketException : Connection reset @ sun.nio.ch.SocketChannelImpl:394

Bug Description

The problem appeared on the version Paper version git-Paper-379 (MC: 1.18.2)
I use a minimum number of plugins on a test sample:
NametagEdit To set a prefix.
ViaBackwards-DEV
ViaVersion-DEV

Steps to Reproduce

The player sets a prefix using the NametagEdit plugin and can no longer log into the server. Command to set the prefix /nte player nik prefix &f&l
This prefix will highlight the player's nickname
There is no error in the console. There is an error in the client logs 1.12.2
Error in his client:

Expected Behavior

I expect you to fix this. This problem can be seen on versions 1.8 - 1.12.2 On version 1.13 and higher this problem does not exist
There is no such problem with the ProtocolSupport plugin

Additional Server Info

I tested the problem without BungeeCord
It appears both on my hosting and on my local computer.

Checklist

• Via plugins are only running on EITHER the backend servers (e.g. Paper) OR the proxy (e.g. BungeeCord), not on both.
• I have included a ViaVersion dump.
• If applicable, I have included a paste (not a screenshot) of the error.
• I have tried the latest build(s) from https://ci.viaversion.com/ and the issue still persists.

I have this same issue too. It is for any special formatted text in chat: underlines, bold, obfuscated text, and links. I am running a 1.19.4 purpur server and only newer players from 1.20.4 get disconnected. I am also using viabackwards and venturechat as those are relevant plugins for chat.

We are waiting for a response from the developers.

Our issue looks similar to this pull request: #3662 hopefully they will fix it soon.
